What Is Mississippi Chicken?

Mississippi chicken is an easy adaptation of the classic Mississippi pot roast, which originally used slow-cooked beef chuck. The flavor profile—ranch seasoning, dry gravy or onion soup mix, pepperoncini, and butter—creates a tangy, savory sauce that became popular for its simplicity and comforting taste. Using chicken keeps the same beloved flavors but shortens cooking time and lightens the meal.

What You’ll Need

  • Chicken thighs – Boneless, skinless thighs are forgiving in the slow cooker and stay moist. Boneless breasts work too if preferred.
  • Ranch dressing mix – One packet adds instant seasoning; you can use a homemade blend if you like.
  • Onion soup mix – Adds savory depth and helps form the sauce.
  • Pepperoncini – Use the jarred peppers and include the juices for tang and mild heat. Jalapeños can be substituted for more spice.
